What is GTU-MultiHIV B?
GTU-MultiHIV B is an investigationalbeing studied as a possible strategy to treat people living with HIV.1 GTU-MultiHIV B belongs to a group of HIV vaccines called therapeutic HIV vaccines.
How do therapeutic HIV vaccines work?
A What is a Therapeutic HIV Vaccine? fact sheet.is a type of vaccine that’s designed to improve the body’s to HIV in a person living with HIV.4 Therapeutic vaccines work by strengthening the to recognize and eliminate HIV from the body. To learn more, read the AIDSinfo
There are several types of therapeutic vaccines currently being studied to treat HIV. GTU-MultiHIV B is a DNA vaccine and is made up of parts of HIV’s genetic information. The HIV genetic information is meant to produce an immune response against HIV in the body. Besides being studied as a therapeutic HIV vaccine, GTU-MultiHIV B is also being investigated to see if it can prevent HIVin people who do not have the .3,5 This vaccine record focuses on the study of GTU-MultiHIV B as a therapeutic vaccine.
Which clinical trials are studying GTU-MultiHIV B?
Study Names: CUT*HIVTHER 001; NCT02457689
Status: This study has been completed.
Location: United Kingdom
Purpose: The purpose of this study was to look at GTU-MultiHIV B vaccine’s safety and ability to produce an immune response in the body when GTU-MultiHIV B was given by two different methods.6
Study Names: VRI02/ANRS 149 LIGHT; NCT01492985
Status: This study is ongoing, but not recruiting participants.
Purpose: The purpose of this study is to find out whether a combination of GTU-MultiHIV B and another investigational therapeutic vaccine called LIPO-5 can produce an immune response in the body that controls levels after treatment interruption.7
Study Names: FIT-06; EudraCT 2005-003071-20
Status: This study has been completed.
Location: South Africa
Purpose: The purpose of this study was to look at GTU-MultiHIV B vaccine’s safety and ability to produce an immune response in the body when GTU-MultiHIV B was given by two different injection methods. Investigators also evaluated if the vaccine had any beneficial effects on participants’ viral load levels and CD4 counts.8–10
Study Names: EHVA T01/ANRS VRI05; NCT02972450
Status: This study is not yet open for participant recruitment.
Purpose: The purpose of this trial is to evaluate the effectiveness of three different strategies in controlling viral load after treatment interruption of ART. The three strategies are GTU-MultiHIV B combined with MVA HIV-B, vedolizumab only, and GTU-MultiHIV B combined with MVA HIV-B plus vedolizumab.11
A Phase I study (NCT01130376) involving GTU-MultiHIV B given in combination with in participants on a suppressive ART regimen has also been completed.12,13

What side effects might GTU-MultiHIV B cause?
One goal of HIV research is to identify new drugs that have fewer side effects. The following side effects were observed in some of the studies of GTU-MultiHIV B listed above.VRI02/ANRS 149 LIGHT (NCT01492985):
In this study, participants were enrolled to receive GTU-MultiHIV B and LIPO-5 vaccines orFIT-06; EudraCT 2005-003071-20: vaccines. A preliminary safety analysis of participants who had received at least one vaccine injection found that a majority of participants experienced at least one side effect, most of which were mild. One participant experienced a serious side effect – arthritis – which was possibly related to (study vaccine or placebo). Among those participants who underwent a treatment interruption of ART, all had . Twenty-three percent of participants had symptoms similar to after treatment interruption of ART, although symptoms were mostly mild. One participant transmitted HIV during the period of treatment interruption.7,14
Results of this study showed no serious side effects related to GTU-MultiHIV B. Local vaccine reactions that occurred immediately or 30 minutes after injections were mild to moderate in severity and were seen more often in participants receiving theinjection than in participants receiving the injection. Examples of local vaccine reactions that occurred include bleeding at the injection site and swelling and hardening of tissue. Other side effects that occurred in participants receiving GTU-MultiHIV B and participants receiving placebo included swelling of , upper respiratory tract infections, and increased blood levels of creatine phosphokinase (an that’s normally found in the heart, brain, and skeletal muscles).8,9,15
Because GTU-MultiHIV B is still being studied, information on possible side effects of the vaccine is not complete. As testing of GTU-MultiHIV B continues, additional information on possible side effects will be gathered.
